Hey Djordje!

I was having this problem yesterday. I have lights (softboxes) in my composition and in almost all the forums they said that I needed to disable the GI and try to emulate the result with more lights in order to get rid of the flickering, but I really liked the way it looked with the GI. I tried Irradiance Cache and QMC (primary & secondary) with the samples set to high and the irradiance cache set to medium. This worked perfectly for me. I had to wait a little bit more for the render, but I left my computer working through the night after I was satisfied with a short LQ preview (It was nothing compared to the rendering time that the QMC +QMC was throwing).

Hope you found a solution!
